Head-to-head evidence
infliximab-qbtx (Ixifi) vs SAR441566
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

infliximab-qbtx (Ixifi)
Marketed by Pfizer
NCT02222493 · Phase 3 · completed
This was a randomized, quadruple-blinded, active-controlled Phase 3 equivalence trial in 650 adults with rheumatoid arthritis taking methotrexate, comparing PF-06438179 with infliximab. The primary endpoint was ACR20 response at Week 14, a clinical disease-activity measure: 61.1% with PF-06438179 versus 63.5% with infliximab, and the reported 95% confidence interval for the difference (-9.92 to 5.11) met the equivalence criterion, indicating no meaningful difference between treatments. This is strong evidence from a well-powered, blinded, controlled trial with a hard clinical endpoint and a met primary comparison.
SAR441566
Developed by Sanofi
NCT06073093 · Phase 2 · completed
The study randomized 264 participants to four SAR441566 dose regimens or placebo and used triple masking of participants, investigators, and outcome assessors. Its primary endpoint was the clinical ACR20 response at week 12, but results have not been posted, so whether the endpoint was met or missed cannot be assessed.
Caveat: this result is taken from a company announcement or a news report of one, not from the trial registry or a peer-reviewed publication. Treat the figures as the sponsor's own statement, not as independently verified evidence.
